Hi, I am getting started writing H5Part files and I am using hdf-1.8.8 and h5part-1.6.5.
When I run a very simple code, attached, I get an error in the H5PartOpenFileParallel which looks like it is an MPI_File_open error. However, in my test code I can open a MPI File just fine.
So, this works,
MPI_File_open(MPI_COMM_WORLD, "foo.mpi",MPI_MODE_CREATE , info, &fh);
but this doesn't
h5file = H5PartOpenFileParallel("foo.h5",H5PART_WRITE,MPI_COMM_WORLD);
This is beyond my ability to figure this out. Any help would be great. This is on a RHEL-6 machine with openmpi-1.5.3-3.el6.x86_64 and gcc-4.4.6-3.el6.x86_64
Thanks
Matt
